MASSIVE MODEL VISUALIZATION IN PDM SYSTEMS

摘要

A method includes storing a massive model database for a product data structure in a product data management server system (100, 220) comprises the steps: - storing (305, 405, 505) a spatial bounding box hierarchy that acts as a spatial index for spatial bounding boxes of a plurality of unconfigured components of the product data structure and storing a cell table that associates cells of the spatial bounding box hierarchy to corresponding component identifiers of the product data structure; - responding (315, 425, 515) to component identifier requests from a client system by sending requested component identifiers from the product data structure to the client system (230), wherein the component identifier requests correspond to visible components of an assembly represented by the product data structure; - transmitting (320, 430, 525) geometric data to the client system (230), the geometric data corresponding to components of the product data structure associated with the requested component identifiers.
